From c349bcade000820be4f53dd2d189887ec11794d4 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Thu, 21 Mar 2019 11:19:46 +0000 Subject: [PATCH 429/725] sound: Fixes for audioinjector-octo under 4.19 1. Move the DT alias declaration to the I2C shim in the cases where the shim is enabled. This works around a problem caused by a 4.19 commit [1] that generates DT/OF uevents for I2C drivers. 2. Fix the diagnostics in an error path of the soundcard driver to correctly identify the reason for the failure to load. 3. Move the declaration of the clock node in the overlay outside the I2C node to avoid warnings. 4. Sort the overlay nodes so that dependencies are only to earlier fragments, in an attempt to get runtime dtoverlay application to work (it still doesn't...)
